MODVERSIONS recently grew a dependency on !COMPILE_TEST so that Rust
could be more easily tested. However, this introduces a Kconfig warning
when building allmodconfig with a clang version that supports RANDSTRUCT
natively because RANDSTRUCT_FULL and RANDSTRUCT_PERFORMANCE select
MODVERSIONS when MODULES is enabled, bypassing the !COMPILE_TEST
dependency:

  WARNING: unmet direct dependencies detected for MODVERSIONS
    Depends on [n]: MODULES [=y] && !COMPILE_TEST [=y]
    Selected by [y]:
    - RANDSTRUCT_FULL [=y] && (CC_HAS_RANDSTRUCT [=y] || GCC_PLUGINS [=n]) && MODULES [=y]

Add the !COMPILE_TEST dependency to the selections to clear up the
warning.
